Description

Technical Field

[0001] The invention relates to a nursing device, in particular to a nursing and training device for limb venous thrombosis. Background Art

[0002] Venous thrombosis is prone to occur in veins throughout the body, and the most common sites of embolism are the veins of the lower limbs and the pulmonary arteries. In particular, due to gravity, blood easily stagnates in the lower limbs, causing the blood in the lower limb veins to be in a high-pressure state. At the same time, there are many venous valves distributed in the veins of the lower limbs, which may intercept blood clots and is an important cause of venous thrombosis in the lower limbs. Secondly, if varicose veins of the lower limbs occur, the venous valves are relatively weak, causing blood stasis, which is also a major factor in inducing venous thrombosis.

[0003] However, the condition of patients with venous thrombosis is unstable in the early stages of the disease. If they engage in conventional aerobic exercise, such as cycling, swimming and walking, it will inevitably make them feel strenuous, which is not conducive to their stability in the early stages. This requires the patients themselves or their families to help them raise their legs and bend their knees while they are lying down, so as to improve the blood circulation in the lower limbs in a targeted manner. This affects the quality of exercise due to the lack of execution of the patients, and prolongs the early care time due to insufficient efforts from their families. Summary of the invention

In addition, in the description of the present invention, the meaning of "several" is two or more, unless otherwise clearly and specifically defined.

[0034] See also Figure 1-Figure 12As shown, the present invention provides a nursing and exercise device for limb venous thrombosis, including a support body 100 for supporting the lower limbs, a pair of power groups 200 installed at the bedside and used to drive the support body 100 to form a flipped state, and a pair of conversion groups 300 for directing power to the support body 100 and switching to a lower limb pressing state; because venous thrombosis often occurs in the lower limbs, the lower limbs are supported by the support body 100, and are driven by the power group 200 to flip up to perform knee flexion and extension exercises. In addition, the conversion group 300 changes the output direction of power so that when the support body 100 supports the lower limbs in a static state, it can press and activate blood circulation, thereby exercising and activating blood circulation in the limbs to prevent venous thrombosis.

[0035] Specifically, the support body 100 includes a support belt 110, a belt winding member 120 wound around both sides of the support belt 110, a belt turning rod 130 and a rotating rod 140 for clamping the front and rear ends of the support belt 110, and a fixed belt seat 150 hinged to the rotating rod 140, that is, the support belt 110 is unfolded by a pair of belt winding members 120, moves between the belt turning rod 130 and the rotating rod 140, and then the whole body can be turned around the fixed belt seat 150 to support the lower limbs for leg lifting exercise; The belt winding member 120 is composed of a rotating shaft 122 and a sliding tube 121 which are connected inside and outside. The support belt 110 is made of rubber and its front ends are connected to the sliding tube 121, and its rear ends are connected to the rotating shaft 122; so that the stretching belt turning rod 130 drives the sliding tube 121 to slide and drives the middle part of the support belt 110 to extend to support the lower limbs.

[0036] Specifically, the power group 200 includes a fan-shaped guide plate 210 clamped on the bedside, a servo motor 240 installed on the outside of the guide plate 210, a transmission rod 220 sleeved with the output end of the servo motor 240, and a sliding rod 230 slidably connected with the transmission rod 220; the transmission rod 220 and the sliding rod 230 are located on the inner side of the guide plate 210, that is, the output shaft end of the servo motor 240 passes through the center of the guide plate 210; the sliding rod 230 is in sliding contact with the inner side surface of the guide plate 210, so that the sliding rod 230 is clamped and limited; the front end of the sliding rod 230 is aligned and connected with the front end of the belt turning rod 130, so that the sliding rod 230 and the belt turning rod 130 extend synchronously; A transmission gear 250 is meshed in the rear half of the sliding rod 230 toward the outside, and the transmission gear 250 meshes with the curved surface of the guide plate 210 toward the outside. A support ring 251 is sleeved in the middle of the transmission gear 250 and is slidably connected to the guide plate 210. Since the guide plate 210 is fixed to the side of the bed, when the servo motor 240 drives the transmission rod 220 to drive the sliding rod 230 to flip around the guide plate 210, the transmission gear 250 meshes with the curved surface of the guide plate 210 and rolls, thereby driving the meshing part of the sliding rod 230 to move, that is, the sliding rod 230 can extend toward the outside during the flipping process, and at the same time drive the flipping rod 130 to stretch the support belt 110 from the thigh to the calf, thereby flipping the flat thigh support, and then driving the calf to perform knee flexion and extension exercises. Compared with the contraction and extension method of the sliding rod 230 and the transmission rod 220 of this device, the fixed-length flip support can save storage and installation space.

[0037] Furthermore, a sleeve 1401 is provided in the middle of one side of the rotating rod 140, and sleeves 151 are provided at both ends of one side of the fixed belt seat 150.

[0038] Furthermore, belt holes 131 are symmetrically provided on the opposite sides of the belt turning rod 130 and the rotating rod 140, so that the rolled-up part of the support belt 110 can be placed in the belt holes 131 for storage; and a belt groove 132 is provided between the tops of each pair of belt holes 131, for guiding the support belt 110 to move horizontally; wherein a plug hole 142 is provided at the center of the inner end of the belt hole 131 on the rotating rod 140, and the rotating shaft 122 is plugged and rotated with the plug hole 142, and a sliding groove 152 is provided on the outer side of the sleeve 151, which is plugged and slidably connected with the rotating shaft 122, so that when the rotating rod 140 and the belt turning rod 130 clamp the belt winding member 120 and the support belt 110 and flip around the central axis of the sleeve 151, the rotating shaft 122 slides and moves in the sliding groove 152; The rotating shaft 122 has cutout grooves 1221 on both sides thereof and along its axial direction to form a limiting structure. The inner wall of the sliding tube 121 is adapted to fit with the cutout grooves 1221 so that when the sliding tube 121 and the rotating shaft 122 slide and retract, the sliding tube 121 can be driven by the rotating shaft 122 to rotate stably, thereby winding or releasing the side portion of the support belt 110.

[0039] Furthermore, a supporting rod 235 is vertically embedded on the inner side of the front end of the sliding rod 230, and connecting sleeves 133 are provided on the side surfaces of both ends of the flap rod 130.
